The Power Supply Exchange Program is not a repair option for power supplies or system fans that have failed or are defective. Its purpose is solely to offer owners of Power Mac G4 (Mirrored Drive Doors) computers the option to reduce the noise produced by their power supplies and system fans by taking advantage of recent improvements to these components.
